Abstract

A rotatable wedge valve mechanism has a valve body or valve cartridge defining a valve chamber and flow ports in fluid communication with the valve chamber. A valve seat is located within the valve chamber in registry with one of the flow ports. A non-rotatable core member having a convex external surface portion is supported within said valve chamber. A wedge member is mounted for rotation within the valve chamber and has a range of rotary motion between open and closed positions of said valve and a non-uniform wall thickness throughout said range of rotary motion. An actuator upon rotary movement achieves opening and closing rotation of said wedge member. A method is provided for machining concave and convex wedge member surfaces from selected center-points to achieve relative thicknesses of wall sections of the wedge member.
